Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

log Koc: > 5 (KOCWIN v2.00)

Key value for chemical safety assessment

Additional information

No experimental studies investigating the adsorption/desorption potential of Tetraesters of pentaerythritol with linear and branched fatty acids are available. Therefore, the log Koc was calculated using KOCWIN v2.00 based on the Molecular Connectivity Index (MCI) (Mayer, 2015). The model has no universally accepted definition of the model domain, but since the substance is outside the log Kow range of the training set of the MCI model, the results should be taken with caution. The definite values may not be fully reliable, but indicate a high adsorption potential, which is also to be expected based on the high log Kow (> 10). Estimations based on the MCI method resulted in log Koc values of 9.27-10.42.
